Wondering whether to use an air fryer or a traditional oven for your next meal? Martin Lewis and his Money Saving Expert team have delved into the debate, offering insights on what’s most cost-effective and energy-efficient.


Air fryers are gaining popularity for their quick cooking times, using a fan to circulate hot air rapidly. They’re brilliant for smaller meals and can be a more economical choice than electric ovens. For example, a 1,500W air fryer might cost around 40p per hour, compared to an electric oven’s 60p. However, if you’re cooking for a crowd – like a big roast or Christmas dinner – your conventional oven might still be the way to go. Larger meals can benefit from the oven’s capacity, making it potentially more efficient despite its higher energy usage per hour.

Gas ovens, on the other hand, come in cheaper at about 23p per hour, though longer cooking times might still tip the balance in favor of air fryers or microwaves. Speaking of microwaves, they’re another cost-friendly option, taking just 7 to 10 minutes to cook a jacket potato for under 3p!
Lewis suggests being mindful of what and how you’re cooking. For single meals or side dishes, microwaves or air fryers could save you money. But when it comes to a feast, the traditional oven’s capacity might be more practical.
For those planning the perfect Christmas spread, energy specialist Llewellyn Kinch recommends using a slow cooker for the turkey and an air fryer for those crispy roast potatoes.
Ultimately, it comes down to what you’re cooking and how many you’re cooking for. Each appliance has its pros and cons, and savvy cooks can mix and match to save on their energy bills while enjoying delicious meals. 🍗🥔✨
